ADFS Explorer

 

Disc Transfer

Google

ADFS Explorer is a program which allows you load floppy disc and hard disc images, view files and copy files to and from your PC's hard disc or other running copies of ADFS or DFS Explorer. If you don't already know, ADFS was one of the disc filing systems used by the Master 128 range of computers.

Hard disc images are used by the excellent BeebEm Acorn/BBC emulator program. Hard disc emulation was added to BeebEm at version 2.3 Beta 3 and further enhanced in version 3. Instructions for using the hard disc images are in the README.TXT file contained within the BeebEm installation file. Hard disc images are also supported by my Mac Port of BeebEm.

Disc images are used by most BBC/Acorn emulator programs. Rather than use the original physical floppy disc with the emulators,  a track by track disc image is made and used instead.

If you still have access to a BBC Computer and a suitable serial lead, you can create a disc image of your old ADFS discs or hard discs using the disc transfer facilities built into ADFS Explorer. Instructions for making up a serial cable are included in the download package below.

Alternatively, there are plenty of ready made disc images of popular programs widely available for download from the internet. Places to try are :

The program will allow you to load or create a new ADFS disc images in any of the following formats :

  •  40T single sided ADFS (S) - adf (160K)
  •  80T single sided ADFS (M) - adf (320K)
  •  80T double sided ADFS (L) - adl (640K)
and
  •  4 Head, 32 Track, 33 Sectors hard disc - dat (1MB)
  •  4 Head, 64 Track, 33 Sectors hard disc - dat (2MB)
  •  4 Head, 128 Track, 33 Sectors hard disc - dat (4MB)
  •  4 Head, 256 Track, 33 Sectors hard disc - dat (8MB)
  •  4 Head, 512 Track, 33 Sectors hard disc - dat (16MB)
  •  4 Head, 1024 Track, 33 Sectors hard disc - dat (32MB)
  •  4 Head, 2048 Track, 33 Sectors hard disc - dat (64MB)
plus it can load a hard disc image of any geometry with a valid .dsc file

After loading a disc image, you will see a screen similar to the one below :

 

It shows the contents of the disc image in a similar way to Windows explorer. You can navigate the folders on the left and selecting them will show the contents of the folders on the right.

You can select files and show their contents in either text, Wordwise, hex or de-tokenised BASIC format (with further options to save or print the displayed file). Directories can also be displayed in *CAT, *CATALL, *EX or *EXALL formats.

You can drag and drop individual files or groups of files to and from your PC or other running copies of the ADFS or DFS Explorer programs.

You can also export whole directories or even the whole disc in one go by use of drag and drop or menu options.

Other options are available for deleting, creating and renaming directories or files as well as setting file attributes, disc boot options and directory titles. Options can be selected off the main menu or a context sensitive menu will appear if you right-click a file or directory name in either window.

Please ensure you have backup copies of your disc images before attempting to modify them.

You can download the latest version of the program below :


To help cover costs, I have decided to make ADFS Explorer shareware at a cost of only 5.00.

If you wish to register the program, please enter the Computer ID and Registration Name below and click the Buy Now button.

Your personalised Computer ID can be found on the Register menu option inside ADFS Explorer.

Your registration key will be returned as soon as I can process the request, usually within 24 hours and normally by return if I am at the computer.

PLEASE NOTE : The Computer ID is valid for one computer only so you will not be able to install the program onto multiple computers without purchasing additional registration keys.

Once registered, all future updates of ADFS Explorer will be free of charge.

If you decide not to register the program, you will not be able to save any disc images you create but all other features will be fully active.
